To all whom t mag/concern: l, 1 i

Be it known that I, WILLARD H. SMITH, of

the city, county, and State of N ew York, haveV y invented certain new I and useful Improvebeing thus established which causes at times a strong current of air to pass upward through the water-closet of the car, carrying with it i waste-paper and bringing with it quantities of .tion of the car, and servesto establish through the closet-funnel a downward draft, which obviates the difficulty hereinbefore referred to.

Various means may be employed to carry my invention into effect.

In the accompanying drawings I shave indicated a few of. the many devices that may be used for the purpose.

Figure 1 is a perspective view of'a railwaycar water closet provided with Ventilating appliances in accordance with my invention. Fig. 2 is a longitudinal vertical central section of the same. Fig. 3 is a horizontal section through the ventilating flue or passage.

The water-closet proper, A, mayV be of any approved construction, with its tubular body extending down through the door of the railway-car. Below the car oor this tubular body is provided in its side with draft-openings a b, each opening into a horizontal tube or funnel, B, which extends longitudinally' of the car. It is through these funnels and openings that the draft is established, which prevents upward currents of airtlirough the closet funnel or seat. ,r i f y. [supposing the carto be moving in the direction of the arrowr in Fig. 3, then vthe front opening, a, should be closed, and the rear openingb, left open. VThe motion of the car establishes a draftV through b and its funnel B, which causes a downward current in the closet sufcient to carry olf all waste-paper and offensive smell, and to prevent dust from entering the .car through the closet to anyV extent. When the car moves in the contrary direction the opening b should be closed and a should be openedin other words, that end of the Ventilating-line which is in front relatively to the imovement of the car should li'e" closed, while the opposite end should be open. Various mechanical devices may be used for this purpose.

Two arrangements are shown in the iigures hereinbefore referred to. In the one arrangement a rotary gate, G, fitting within the tubular body of the closet, is provided with ports or openings c d, so formed and arranged that when the'one port is opposite one of the openings in the closet-body a solid portion of the gate will be opposite to and close the opposite opening in the closet-body, as indicated plainly in Fig. 3. The rotary gate can readily be operated by any suitable means-as, for instance, by a crank-shaft, e, which extends inside the car, andis provided with a handle, e', by Y which it may be turned, and at its lower and outer end is provided withv a crank-arm, which enters a slotted bracket-arm, f, fast to the rotary gate.

In lieu of the rotary-gate arrangementl can employ doors g on the ends of the draft funnels or flues B, which can be closed or opened, as the case may be, according to the direction in which the car moves. In this case, perhaps, waste-paper might accumulate in the closed front liuc/or funnel, B; but this tendency canl partly be `neutralized by connecting thefun- IOO Fig. 4 is a longitudinal vertical central section of a closet containing the modification. Fig. 5 is a plan, partly in horizontal section', of the same. Fig. 6 is a horizontal section through the lower portion of the closet-body.

The said lower portion of the closet-body is in this instance rectangular in cross-section. Its draft-openings a b are provided with hinged doors i, one of which should be closed when the other is open. For this purpose each is provided with a pin, j, which projects through and works in a curved slot, k, in the closetframe, and is connected by a link, If, to the crank-arm m of a shaft, n. When the crankshaft u is turned it will, in closing one door, open the other.

A bow-spring, o, or other friction device may be used to hold the parts securely in either position of adjustment.

I-Iavingdescrihed my nven tion, I would say, in conclusion, that I do not confine myself to the mechanical details herein shown in illus-- tration of the same; but

y movement of the oar may be closed, substantially as and for the purpose set forth.

2. The combination, with the tubular closetbody provided with the front and rear draftopenings, of a draft flue or funnel for each opening, and doors by which said openings may be closed at pleasure, substantially as and for the purposes set forth.

In testimony whereof I have hereunto set .my hand this 3d day of December, 1879.
